1 Claim.

This invention relates to window scaffolds and more particularly to a back rail therefor.

It is an object of the present invention to provide a window scaffold with a back rail which can be detached from the window scaffold when the window scaffold is to be stored and which can be folded to consume little space.

Other objects of the present invention are to provide a combined window scaffold and back rail which is of simple construction, easy to install on the window, has minimum parts, formed of rod or pipe, inexpensive to manufacture and efiicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view of the window scaffold with the back rail attached thereto.

Fig. 2 is a side elevational view of the scaffold with the back rail thereon and the scaffold assemble-d within a window opening.

Fig. 3 is a top plan view of the combined scaffold and back rail.

Referring now to the figures, represents a window scaffold formed of a continuous rod or pipe bent into U-shape as indicated at H having a closed portion I2 and legs 13 bent back at [4 and threaded on their free ends as indicated at l5. The bent back portions of the legs are braced against portions of the legs adjacent the closed end portion 12 by braces l6 welded to the leg portion at the points of their connection therewith.

A long pipe I! is extended onto the threaded portions of the legs and retained in place by nuts It. This pipe engages the inner face of the window frame l9 while the closed end portion l2 engages with the exterior of building wall 2| below window sill 22.

A seat formation 23 is connected between bent portions I3 of the scaffold legs. On these bent portions l3 and. extending through the seat 23 are welded at opposite legs, two longitudinally spaced eyes 24 and 25. The eyes 25 receive a U-shaped back rail member 26 having laterally spaced loops 2! and 28 on its upper end and hook formations 29 adapted to enter the eyes 25 to be retained thereby at the rear of the window scaffold. At each side of the member 20 and attached to the respective loops 2'! and 28 are braces 3| having outwardly bent ends 32 adapted. to extend through the eyes 24 and be secured therein by cotter pins 33. The back rail thus comprises the U-shaped member 26 and the braces 3|.

By detaching the bent end- 2 32 of the braces 3| from the eyes 24 and the hook formations on the leg portions of the U-shaped member 26 from the eyes 25, the entire back rail can be removed from the window seat and the braces 3| folded upon the member 26.

The window scaffold can be easily pulled into the window when not being used without the disengagement of any of the parts. The back rail parts when removed from the window scaffold can be folded together and will consume little space. This back rail will form protection for the person using the scaffold and as a back rest against which the person may lean while working on the window. This back rail makes the window scaffold a safe device. The user of the scaffold cannot now fall backward from the scaffold.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

I claim:

A window scaffold comprising a continuous rod bent into a U-shaped member having a closed portion and leg portions, each of said leg portions being bent to form a pair of parallel V- shaped portions having a top leg portion and a bottom leg part, a brace member extending between and secured to the leg parts of each leg portion, means adapted to secure the top leg parts to the inner side of a window frame, longitudinally spaced front and rear eye formations on each top leg part, a U-shaped back rest having leg portions with detachable hook formations engaged in the rear eye formations of the top leg parts brace members each having an eye end and a bent end, said U-shaped back rest having loops laterally spaced from one another at its upper end, said brace members extending respectively from the said detachable engagements of their bent ends with the front eye formations tohinged engagement with the loops on said U-shaped back rest by means of their eye ends, and a seat on the top leg parts.
